Abstract (en)
[origin: EP0369730A2] A liquid crystal display provides a high quality color image and efficient energy utilization. A layer of liquid crystal material (24) is controlled by a transparent electrode matrix (2). A matrix (20) of (primary color emitting) phosphors, each in alignment with a transparent electrode, is fixed to a surface of a fiber optic plate (18). A source of fluorescent energy excites the phosphors. A filter (14) located behind the fiber optica plate reflects visible light, both ambient and that emitted from the phosphors. The fiber optic plate (18) acts as a relay lens and prevents cross pixel color contamination while the generation of backlight by the phosphor conversion of fluorescent to visible energy is a highly efficient process.
